Yarn - Command yarn import error: This package doesn't seem to be present in your lockfile; try to make an install to update your resolutions

Question

我正在寻找在我的项目中同时使用 yarn 和 npm，如果我发现 yarn 对我的特定情况有用，我可以将我的项目移动到仅使用 yarn。

然而，$yarn import 出现以下错误：

local:project_middleware jgil$ yarn import

Internal Error: project-middleware@workspace:.: This package doesn't seem to be present in your lockfile; try to make an install to update your resolutions

我已经运行 $yarn set version berry 并一次又一次地尝试删除 node_modules 目录、运行ning npm install 等不同组合. 没有任何东西可以使它工作...不知道缺少什么。

会不会是 Node.js 的版本或我正在使用的任何其他组件的问题？

Answer 1

此处的问题似乎是其中一个工作区内现有的 yarn.lock 文件。删除它解决了问题。

更多信息：

示例：3 个工作区：2 个 create-react-app (app, home) 和一个共享组件：(components)

在 component 文件夹中存在一个挥之不去的 yarn.lock 文件。删除它。

同时检查：

您所有的工作区在其每个 package.json 中都有 "private": true（与 name、private、source 相同级别）。
检查您是否已将工作区添加到主 package.json

"workspaces"

当您执行 yarn workspaces myworkspace 时，myworkspace 与您在 package.json 中的工作区名称相匹配。在我的例子中，components 文件夹内的工作区名称称为 @schon/components，因此我需要将其命名为 yarn worksapces @schon/components。

Answer 2

同样的错误出现在我身上，我发现我错误地添加了.yarnrc.yml。在 yarn-berry.cjs 中删除文件及其引用后，我得到了解决方案和项目运行
